Engine code question

Found the number on my '62. Is the number supposed to match the vin? Mine does not. The engine is stamped 4J318945. How do I decifer the number?

I did look there. Engine info doesn't match either.

 

I have been searching before posting. Engine info wasn't real clear.

 

Can't help you with specific meaning of the numbers, but the numbers won't match the chassis.

Very true Dave. A lot could have changed since 1962!

 

Some States back in the day used the engine number for titling purposes instead of the serial number on the firewall and chassis. I have come across this a few times. I have an original New Jersey title for one of my Willys wagons with the engine number as the id. The problem is the guy I bought it from swapped a 327 Chevy in back in the early 1970's. When I went to get a title, I found I was out of luck. The original alloy id tag is still in place in the footwell, but nothing matched.
I was never able to tie engine numbers to vehicle id.
